Troubleshooting Guides

1. Stream Connection Errors (RTSP / ONVIF)

If you see a black screen or connection drop, check the following:

• Camera Accounts: Most cameras (such as Tapo, VIGI, Wyze) require you to create a specific "Camera Account" username and password for local streaming inside their mobile app. This is separate from your cloud login.
• IP Address Verification: Verify your camera's local IP address in your router or mobile app (e.g. 192.168.1.50). Cameras can change IPs upon reboot unless assigned a "DHCP Reservation" / "Static IP".
• ONVIF Ports: Standard ONVIF ports are usually 80, 888, or 8080. If the app cannot scan PTZ capability, check your camera model in our universal database.

2. Microphone & 2-Way Intercom

If the microphone talk-back intercom is not transmitting audio:

• Confirm that Windows microphone permissions are granted for OpticLink Pro.
• Verify your camera supports RTSP/ONVIF backchannel voice audio (available on compatible hardware models).

3. Universal Streaming Server Setup

If you cannot stream your cameras to your TV or PC browser:

• Ensure both devices are connected to the exact same Wi-Fi or wired network.
• Make sure your Windows Firewall is not blocking the application's local port broadcasting.
